Problems solved by technology

[0002] Existing tools for extinguishing forest fires at present are all portable two-stroke gasoline fire extinguishers. The biggest disadvantage is the use of gasoline. Because the temperature of the fire scene is relatively high, gasoline is a flammable substance and has a high potential safety hazard. In addition, it wastes energy and pollutes. The environment and noise are loud. After a tank of oil is used for 30 minutes, it is necessary to refuel in time and the long refueling time will affect the fire extinguishing. The effective use time of a single time is short. The complex mechanical structure causes many parts to be prone to failure or damage, which affects the effect of fire extinguishing as a whole

Embodiment 1

[0016] A portable high-efficiency energy-saving electric wind fire extinguisher, which consists of: fan 1, the middle position on the left side of the fan is connected to the brushless motor 2 through bolts, and the brushless motor is connected to the centrifugal impeller 5 shafts inside the fan through the shaft connection, the inside of the centrifugal impeller is equipped with a suction port 6, the end of the suction port is fixed with a protective net 7, the upper left side of the fan is fixed with a controller 3, and a power supply is installed inside the controller , the upper part of the controller is equipped with a liquid crystal display and operation buttons.

Embodiment 2

[0018] According to the portable high-efficiency energy-saving electric wind fire extinguisher described in Embodiment 1, one end of the brushless motor is connected to one end of the horizontal horizontal handle 8 by bolts, the right side of the fan is connected to the other end of the horizontal horizontal handle by bolts, and the horizontal A vertical right handle 9 is installed on the right side of the horizontal handle.

Embodiment 3

[0020] Utilize the fire extinguishing method of the portable high-efficiency energy-saving electric wind fire extinguisher described in embodiment 1, at first adopt brushless motor as power, no-load speed reaches 12000rpm, rated speed reaches 10000rpm, controller controls the rotation of brushless motor, inside the controller Equipped with speed regulation, over-current, over-voltage and under-voltage protection circuits, and internally equipped with a lithium battery as a power supply, the controller is equipped with an LCD screen and operation buttons on the outside, which are used to quickly check and adjust various operating conditions during work. Parameters, secondly, the brushless motor drives the fan to generate fire-extinguishing wind. The fan is a centrifugal fan. According to the blade shape and curve angle of the high-pressure theory of the aircraft, the shape, angle, and linearity of the impeller are calculated by high-precision computers to obtain accurate data. G...

Abstract

The invention relates to a portable efficient energy-saving electric pneumatic extinguisher. At present, current forest fire extinguishing tools are all hand-held two-stroke gasoline extinguishers, which have the greatest disadvantages that very high potential safety hazards exist on fire scenes and energy waste, environmental pollution and much noise are caused as gasoline and engine oil are used, the single-unit weight is heavy and the single-use time is short. The portable efficient energy-saving electric pneumatic extinguisher comprises a fan (1) and is characterized in that the middle position of the left side of the fan is connected with a brushless motor (2) through bolts, the brushless motor is in shaft connection with a centrifugal impeller (5) in the fan through a shaft, an exhaust opening (6) is mounted in the centrifugal impeller, a protective net (7) is fixed at the end part of the exhaust opening, a controller (3) is fixed at the upper part of the left side of the fan, a power supply is mounted in the controller, and a liquid crystal screen and operation buttons are mounted on the upper surface of the controller. The invention provides the portable efficient energy-saving electric pneumatic extinguisher.

Description

Technical field: [0001] The invention relates to a portable high-efficiency and energy-saving electric wind fire extinguisher and a fire extinguishing method. Background technique: [0002] Existing tools for extinguishing forest fires are all portable two-stroke gasoline fire extinguishers. The biggest disadvantage is the use of gasoline. Because the temperature of the fire scene is relatively high, gasoline is a flammable substance and has a high potential safety hazard. In addition, it wastes energy and pollutes. The environment and noise are loud. After a tank of oil is used for 30 minutes, it is necessary to refuel in time and the long refueling time will affect the fire extinguishing. The effective use time of a single time is short. The complex mechanical structure causes many parts to break down or be damaged easily, thus affecting the fire extinguishing effect as a whole. Invention content: [0003] The object of the present invention is to provide a portable hig...
